If "better" doesn't mean better voltage regulation, better ripple suppression, Corsair Link integration, etc... then you're correct.
But last I checked, ALL of those things matter when comparing one PSU to another. For the record: The AX860 is the same PSU as the SS P-860. And yet the AX860i is more expensive than the AX860. Hmm....
Try reading some PSU reviews so you can figure out that there's more to PSUs than wattage and 80 Plus rating.
